A flexible silicone obturator is an alternative to the acrylic resin obturator. It can be useful for patients with severe trismus who cannot insert a large prosthesis, as the flexibility of the hollow silicone section allows easy placement and removal (Fig. 9). Other patients cannot tolerate an unyielding substance against sensitive nasal tissues. Silicone can provide the necessary comfort without compromising retention. Silicone obturator sections can often be modified when further surgery is needed and result in a savings of time and expense (Fig. 10). For patients who can be reevaluated only twice a year, several silicone obturator sections can be made initially. One can be used while another is being cleaned or duplicated.
柔性硅橡胶阻塞器是丙烯酸树脂阻塞器的一种替代选择。对于因严重牙关紧闭而无法插入大型修复体的患者，它可能很有用，因为中空硅橡胶部分的柔韧性便于放置和取出（图9）。其他患者无法耐受坚硬物质接触敏感的鼻腔组织。硅橡胶可以提供必要的舒适度，同时不影响固位。当需要进一步手术时，硅橡胶阻塞器部分通常可以进行修改，从而节省时间和费用（图10）。对于每年只能接受两次重新评估的患者，可以一开始制作多个硅橡胶阻塞器部分。一个可以在使用，而另一个可以进行清洁或复制。
